In the post-$localize world the current locale value is defined by setting
`$localize.locale` which is then read at runtime by Angular in the provider
for the `LOCALE_ID` token and also passed to the ivy machinery via`setLocaleId()`.
The $localize compile-time inlining tooling can replace occurrences of
`$localize.locale` with a string literal, similar to how translations
are inlined.
